wow !
so much usefull information ,
Thank you all , for supporting me
specially Rich and Jean :>

The time I found that some RPC ports are open
on systems , the same idea came across my mind
but had no idea what to to/where to begin. 
I had the secuityFriday PoC but to be honest never
completely reviewd their paper :p
and thank you Jean for scheduling service hint
which will save me time .

and , Dave 
Can you explain more about fingerprinting based on
COM ojects ? any hint/paper/refrence to review ?

regards
-Hamid

One thing CANVAS does to determine random things is
fingerprint COM 
objects present on remote systems. This can often
tell you if a certain 
software package is available or not. I haven't seen
anyone else do this 
yet, but it's not that hard...

Cheers for the explanation for the lack mstask.exe
UUID's in 2k3 SP1 and
the links :)

It was Urity's presentation which set me off down
the road of looking
at/implementing RPC fingerprinting in the first
place :), after the
presentation I thought more people would
investigate the
technique.......doesn't seem like many people have,
however I find it
quite a useful technique in many situations.

-- SP1 does not show endpoint UUID data for the
mstask.exe whereas SP0
has quite a number of entries (typically 20+).
     

Right, in Windows Server 2003 SP1, the Task
Scheduler service
(mstask.exe process) does not register its RPC
services on the
ncacn_ip_tcp transport but only on the ncacn_np
transport (\pipe\atsvc):

Urity gave in 2004 a presentation on the subject
of fingerprinting systems
looking at registered RPC interfaces, you might be
interested in looking
at the RpcScan tool and the related presentation:
